BENJAMIN S. BURRELL, OF INDIANA HARBOR, INDIANA.

LIQUID-FUEL-GASIFYING APPARATUS.

To all whom it may concern:

Be it known that I BENJAMIN S. BUR- BELL, a citizen of the United States, residing at Indiana Harbor, in the county of Lake and State of Indiana, have invented a new and useful Improvement in Liquid-Fuel Gasifyi'ng Apparatus, of which the following is a specification.

The primary object of my invention is to provide an apparatus for gasifying liquid fuel, such as the heavy residue of petroleumdistillation known as fuel oil or tar, to better adapt the fuel for industrial-furnace heating, or for storing the resultant gas to be supplied from storage for the same use and for other purposes.

In the accompanying drawings, Figure 1 is a broken and partly sectional view showing my improved apparatus in elevation as applied to an open-hearth furnace, of which only a portion is represented; Fig. :2 is an enlarged section on line 2:2, Fig. 1; Fig.

3 is an enlarged section on line 3-3, Fig.

1; and Fig. 4 shows my improved apparatus by a view in side elevation connected with a gas-washer and modified to adapt it for the manufacture of fuel gas for storage.

Referring more particularly to Fig. l, a liquid-fuel'pipe 5 leads from a source of supply (not shown) which should be under pressure of up to, say, 120 pounds to the square inch and has valved branches 6 each terminating in a spraying nozzle 7. A gas-generating or mixing-chamber 8 is, provided along its top and its opposite sides with series of funnels 9, into the outer ends of which the branches extend to place the nozzles at the narrower ends of the fun nels and cause the latter to protect the noz- Zles from the intense heat in the chamber 8. This chamber is heated with superheated steam introduced by a pipe 10 from a suitable source of supply (not shown) through the head 11 of a depending conduit 12 open to the outer air at its lower end, where it is providedwith a regulating valve 12*, this conduit having a lateral branch 13 containin a regulating valve 13 and connected wlth the gas or hot-air chamber 14 of the furnace 15. The head 11 is formed with a flaring mouth 11", at which it meets and is connected with the rear end of the chamber 8 and which is properly proportioned to permit expansion of the steam, air and gas to fill the chamber. The steam pipe 10 ex- Specification of Letters Patent.

tends in the head 11 short of the mouth 11, but past the upper end of the conduit 12 to exert an injector-action on the conduit and branch 13 and draw cold and hot air, either or both, in quantities regulated by the valves 12 and 13 into intermingling contact with the steam and thereby decrease the amount of the latter to be used.

The sprays of oil introduced under pressure through the nozzles 7 and the funnels 9 into the generating chamber 8 in directions at right-angles to or crosswise of the heating fluid-currents from the'mouth 11, traverse these sprays, which are thereby brought into such thorough and intimate contact with the heating medium as to become gasified and flow as gas through a conduit 16, which may be a tubublar extension of the chamber 8 and affords a burner for the hot gas, directing its flame into the hearth of the furnace.

As will be understood, the gaseous form of the fuel is preferable to the liquid form thereof, not only because, of the practical difficulties in properly controlling the feeding of the fuel in liquid form, but because the heat of the latter in burning is largely expended after passage through the urnace, while the heat from burning gas is mostly expended in the furnace.

If instead of gasifying the liquid fuel for the described furnace-heating purpose, the gas is designed to be used for storage or directed to any gas-feeding line, my improved apparatus is employed in its modified form,

illustrated in Fig. 4. The modification consists in omitting the vertical conduit 12 with its valve 12 and the lateral valved branch 13, since when the gas is to be stored as fuelgas'no admixture of air is to be used; and the conduit 16 then shorter than the burner 16, discharges through a flaring mouth 17, into a gas-washer or cooler 18, of any suitable construction, having a tapering outlet-chamber 19 from the apex of which a gas-discharge conduit 20 leads to a gas-line or gas-holder (not shown). In the modified form of the apparatus, the head 11 is a mere tube.

I realize that considerable variation is possible in the details of construction thus specifically shown and described, and I do not intend by illustrating single specific embodiments of my invention to be limited thereto, my intention being in the following claims to claim protection upon all the novelty there may be in my invention as fully as the state of the art will permit.

I claim:

1. A liquid-fuel gasifying apparatus comprising a gas-generating chamber having a conduit at its discharge end and provided with longitudinal series of spraying-non zles angularly disposed with reference to said chamber and discharging therein, a liquid-fuel feeding-conduit having branches each leading to a spraying-nozzle, a tube meeting the inlet-end of said chamber, and a steam-supply pipe extending into said tube.

2. A liquid-fuel gasifying apparatus comprising a gas-generating chamber having a conduit at its discharge-end and provided with longitudinal series of spraying nozzles angularly disposed With reference to said chamber and dischargin therein, a liquid-fuel feeding conduit having branches each leading to a spraying-nozzle, a tube having a flaring mouth meeting the inletend of said chamber, and a steam-supply pipe extending into said tube.

3. A liquid-fuel gasifying apparatus, comprising a gas-generating chamber having a conduit at its discharge-end and provided with longitudinal series of funnels, a liquidfuel-feeding conduit having branches each leading into the narrower outer end of a funnel and terminating therein in a nozwith series of .funnels along its top andsides, a liquid-fuel-feeding conduit having branches each leading into the narrower outer end of a funnel and terminating therein in a nozzle, a tube having a flaring mouth meeting the outer end of said chamber, and a steam-supply pipe extending into said tube,

5. A liquid-fuel gasifying apparatus comprising a gas-generating chamber having a burner-forming conduit at its discharge-end for directing the flame into a furnace and provided with longitudinal series of funnels, a liquid-fuel-feeding conduit having branches each leading into the narrower outer end of a funnel and terminating therein in a nozzle, a valved air conduit having a valved lateral hot air branch extending from it for connection With the hot-air cham ber of a furnace and terminating at its upper end in a head having a flaring mouth meeting the inlet-end of said chamber, and a steam-supply pipe extending into said head past the discharge-end of said air-conduit.
